"Please give me your identity token. The old man put away his bow and arrows and quiver and said to Ning Caichen.

Ning Caichen sent it as he said, and once again put his eyes on his spatial ring, summoned all kinds of blades obtained from killing people and looting treasures, and piled them up into a small mountain on the ground: "And these, please exchange them all for me." ”

The old man cast a spell and sucked all the blades on the ground behind the counter, and after examining it, he said, "The total is worth five hundred and eighty-eight points, please decide whether to exchange it." ”

"So many?" Ning Caichen was taken aback by this number and said in surprise.

The old man glanced at him faintly, but there was no squeak.

"Then let's redeem it. Ning Caichen didn't feel so embarrassed, and said to him.

The old man nodded, and then put all these things away: "Excuse me, is there anything else to exchange?"

Ning Caichen thought for a moment and said, "Can the exercise cheats be exchanged?"

"As long as there is nothing in the academy, everything will be valuable. The old man said succinctly.

Ning Caichen was stunned, summoned the God of War Marksmanship Innate Chapter from the space, and handed it to the counter: "Look, what is the value of this exercise?"

"No. The old man glanced at the name of the exercise, immersed his divine thoughts in a piece of jade, browsed it, raised his eyes and said, "We have the complete version of this piece of marksmanship here, so this one of yours is worthless." ”

Even if what the other party said was the truth, the cold voice still made Ning Caichen feel very upset.

"Now you have a total of six hundred and eight credits on your identity token, can you continue to redeem it?" the old man said.

Now that the chicken rib weapon on Ning Caichen's body has been disposed of, and if he exchanges it, he will have to sell the elixir and elixir, or the immortal scripture that he got from the princess Qiqi. And no matter which of these three categories, he can't bear to deal with it.

"Six hundred and eight credits, you should be able to exchange it for two good beast blood. Ning Caichen thought in his heart, waved his hand and said, "I won't exchange it for the time being, and I'll come back when the credits are not enough." ”

Walking out of the credit exchange office with his identity token, Ning Caichen came to the mission hall again.

"The exchange is complete?" said Xiushi, who had just received him, greeted him with a smile when he saw him.

Ning Caichen came to the bench in front of his window and sat down, and said, "Is there high-quality demon beast essence blood in the storehouse?"

Xiushi nodded and said, "There are a lot of demon beast essence blood, may I ask how high the high quality you mean?"

Ning Caichen opened his mouth and asked, "How tall is the highest?"

"Because the demon beast essence blood in the library also comes from the exchange of the academy disciples, the highest quality beast blood is only the essence blood of the old demon of the Yuan Infant Realm. ”

"Yuanying Realm!" Ning Caichen imagined the strength of the old demon holding the mountain alone, even if he knew in his heart that he would never be able to afford this kind of essence blood, he couldn't help but ask: "How much is this essence blood worth?"

"Because the quantity is relatively rare, each drop is worth 30,000 exchange points, do you want to exchange this essence blood?"

Ning Caichen was choked by the price of 30,000 yuan, and almost cried out without losing his voice. He killed people and grabbed treasures and accumulated countless blade magic weapons, so that he could sell them for five or six hundred exchange points, and now a drop of essence blood actually costs 30,000, which is too outrageous.

"This ...... Well, Xiushi, are you sure you're not joking with me, 30,000 exchange points? That's 30,000 credits, and if you overtime, you can soak in the library until you die. ”

Hearing his deep voice, the Xiushi's expression remained unchanged: "To be precise, you can't die of soaking." Because the rules of the library are that if you don't have permission, the longer you stay, the more credits you will consume. After three or five years, the required credits can be called almost astronomical, and a few drops of Yuan Infant Realm essence blood can't make up for it. ”

Ning Caichen was stunned, waved his hand speechlessly and said, "Okay, let's not talk about this for the time being." In addition to the essence blood of the old demon in the Yuan Infant Realm, what other essence blood is not in the library?"

"There are a total of the essence blood of the old demons in the four realms of Yuanying, Jindan, Zhuji, and Qi refining. Among them, the essence blood of the Yuan Infant Realm is scarce, so each drop is 30,000. The rest of the blood is sold by the bag. The quality of the essence blood in the Jindan Realm varies, and the price ranges from three thousand to five thousand. There are more types of essence blood at the foundation level, and the price ranges from three hundred to eight hundred. The same is true for the essence blood of the Qi Refining Realm, where the price ranges from one hundred to three hundred. You can choose what level of essence blood you want to exchange. Xiushi spoke.

Compared with this price, Ning Caichen remembered the pitiful six hundred points in his identity token, and his heart was suddenly filled with bright sadness: "Which is better, the Qi Refining Realm essence blood worth three hundred points, or the Foundation Building Realm essence blood worth three hundred points?"

Xiushi opened his mouth and said, "Of course, the essence blood of the foundation building realm is better. The cultivation realm, one realm and one heavy heaven, the breakthrough of each major realm, while cultivating to improve, will also improve to the quality of blood. ”

Ning Caichen pondered for a long time, and handed over his identity token with some pain: "I want two copies of the essence blood of the foundation building realm, worth three hundred exchange points." ”

As Xiushi took his identity token and sent it back, the six hundred and eight credits on Ning Caichen's token were suddenly only a fraction left, and there were still eight points.

The only consolation is that each of the exchanged blood bags is the size of a palm, and it is definitely more than enough to build a spirit array in the palm of the hand.

Almost running away, he walked out of the mission hall and left the exchange peak, Ning Caichen walked through the sky and quickly returned to the White Stone Palace.

Placing both blood bags on the ground, Ning Caichen opened one of them and summoned the Human Emperor Pen, stained with blood and cut out a pattern in his palm.

Because the wounds on his body caused by the Human Emperor Pen would heal quickly, this caused the wounds he had opened to disappear in a very short period of time, leaving only the blood of the demon beast essence and his own blood mixed together in the palm of his hand, forming a pattern of lines.

When the sun set and Xiao Qian flew out of the jade pendant space for a long time, Ning Caichen finally engraved the complex and changeable refining formation in his right hand, and the silk threads were combined into a small and exquisite array, like a tattoo.

Feeling that after the formation of the formation, the true qi instilled into the palm of the hand will no longer dissipate with time, and even the heaven and earth aura that can be absorbed through the formation will increase, Ning Caichen's face finally bloomed with dazzling light, stood up, hugged Xiao Qian, who had been waiting for a long time, turned around, and said happily: "Xiao Qian's wife, we have succeeded." ”

Xiao Qian's body rotated with his body in mid-air, and only his existence remained in the whole person's field of vision, the corners of his mouth were slightly hooked, he stretched out his arms to hug his body, and his laughter sounded like a silver bell: "Well, Xianggong...... We did it. (To be continued.) )
